SPECIFICATION forming part of Letters Patent No. 502,922, dated August 8, 1893. Application filed May 3l, 1892. Serial No. 434,895. (No-model.)

To @ZZ whom it may concern:Y

Be it known that I, NmLsv ANTON CHRIsrEN- SEN, a subject of the King of Denmark, resid'- ing at Chicago, in the county of Cook and State 0f Illinois, have invented a certain new. and useful Improvement in Condensing Api paratus, which is fully set forth in the following specification, reference being had to'the accompanying drawings, in which- Figure l is a plan view of my vimproved condensing apparatus, embodying my invention. Fig. 2, is a vertical longitudinal secf tion of the same, taken on the line 2-2, of Fig. l. Fig. 3, is a detail cross-section of the same, taken on the line 3 3, of Fig. 2, and looking in the direction of the arrow. Fig. 4, is a detail cross-section, taken on the line 4-4, of Fig. 2, and looking in the direction of the arrow. Fig. 5, is a rear elevation of the double disk or shell, detached; and Fig. 6, isa detail section of the shell and the central partition. Figs. 5 and 6 are on an enlarged scale.

My invention relates to improvements in centrifugal pumps for exhausting steam from engines, or vacuum pans in distilleries, or from any machine using steam where it is desirable that the steam should be exhausted; and my improvement consists in the arrangement in a chamber of the pump of a double disk or shell, cone-shaped, with its inner surfaces converging vas they extend outwardly, in such a manner as to leave a thin wedgeshaped opening between the inner and outer disks of the shell at their outer edges, with partitions between the disks also curving and secured to the inner surfaces of the disks and holding them in their proper position, the whole forming a kind of turbine-wheel acting inversely, so that instead of'obtaining power by water falling on the wheel, water may beV raised by applying a power to the shell, so

that condensed steam or water may be thrown from the condensing chamberinto an adjoining chamber, in which the air orV gas and water being completely separated, the water iiows out through `a discharge pipe and thev air escapes through a ventilator connected with said chamber.

My invention consists further in the arrangement of inlet steam pipes with coldl water pipes, so arranged as to iiow into the irst chamber in the pump'at the same time;

and in various wallspor partitions in said pump, so separating the different sections that the water and airv or other gases can be Withdrawn by the action of the blades arranged in the disks as hereinafter-stated, and my invention consists of other devices hereinafter described.

In the drawings, A represents the outer cas ing of a centrifugal pump containing my invention. This chamber A is dividedinto two compartments B-C.

D is a steam inlet pipe, broken at the top. It is directly connected with the chamber con.- taining the steam which is to be exhausted.

VF is a pipe connected with a cold waterpipe and which opens by means of a suitable valve controlled by the operator into the Steam pipe D, for the purpose of condensing the descending steam by a stream of cold water flowing into it. The chamber B receives the condensed steam.

F is a partition or wall dividing the chambers B and C. This partition has openings f-f through which the water and air with other gases are drawn from the chamber B into the chamber C, as hereinafter stated.

All the different parts are of metal, preferably iron or steel. The pump case A has an opening, ot, in its surface. This opening is covered by the removable cap, A', and is for the purpose of obtaining access to the interior of the casing and the devices therein contained.

F is a diaphragm or division platewith its lower end attached to and extending in a curve a short distance from the partition F at the lower part of the opening f and thence vertically until it reaches a point between the upper end of the opening f and the casing A, as clearly shown in Fig. 2. The casing A, partition F and diaphragm F may be cast in one piece.

F2, is a hood attached to and supported by the partition-F as shown in Fig. 3. The Water from the chamber B rises intothe hood F2 through the opening f in the partition F until it reaches the double disk, or wheel, H, by which it is forced into the chamber -C by centrifugal force, as hereinafter described.

G, is a shaft, having a bearing at its inner end in the pedestal, a', which rests upon and vis secured by any suitable means to the partition F. The shaft G at its outer end ex- IOO tends through the stuffing box, g', in the casing A and has a bearing at its outer end in the bearing box, @which is rigidly secured to the platform, b', at the end of the casing A, as shown in Fig. 2. The shaft G is driven by a pulley, g, as shown in Fig. 2, or it may be actuated by any suitable means.

On the inner end of the shaft Gis mounted the double disk or shell II, which is rigidly secured by any suitable means to it. This shaft is reduced in size and forms a shoulder to assist in holding the shell II in position. The end of the shaft is screw-threaded and adapted to receive a nut, h', and the shell II is secured between the shoulder and the nut 7i. The shell Il is composed of two disks, which may be designated as an inner disk, h2, and an outer disk, h3, which are con uected with each other by partitions, h4. Both disks and the partitions are, or may be cast in one piece, as shown in Fig. 2. The inner disk 7'1.2 is directly mounted on the shaft G and the outer disk h3 is held in its position by the partitions h4, which separate the disks and are at right angles to each disk at any given point. The disks h2 and haare separated from each other at their inner edges or ends, the distance being regulated by the size of the shell required and each disk curves outwardly from its inner edge on different curves, so that there is only a thin wedge-shaped opening between the two disks at their outer edges through l i mounted on suitable bearings,a cone-shaped shell composed of an outer and inner disk, curved outwardly on different curves and 1 separated from each other by a space gradually diminishing in width outward to a thin slit extending around their outer edges, and

which wateris, or may be thrown. Both disks are concave on their upper surfaces. There may be any number of partitions h4; I have shown four in the drawings. The partitions h4 conform in their shape to the curved surfaces of the outer and inner disks of the shell H, being wider at their inner ends and gradually coming to a point at their outer ends. The inner end of the shaft G is placed at such a distance from the partition F, and the shell or wheel H is so mounted on its shaft, that whatever the size of the shell or wheel may be, the outer edges of the disks h2 and h3 will extend very near to the inner end of the partition F, leaving only a small opening, z", as shown in Fig. G, for the passage of the air and other gases, which are drawn or sucked by the action of the shell H over the diaphragm F', (which does not extend to the top of the casing A) and into the openingffrom which it is drawn off by the water that is thrown out by the shell or wheel, as before stated, into the chamber C. As before stated the water which rises into the hood F2 is drawn from thence or sucked into openings t' between the disks 71,2 and ha of the shell or wheel H and is thrown out of the shell or wheel Il between the outer edges of the disks and into the chamber C.

A waste pipe, L, is provided in the chambetl C through which all surplus water, accumulated in this chamber, will, afterit reaches a certain height, pass off out of the pump.

M is also a pipe opening from the chamber C through which the air and other gases,

thrown into the chamber C, may be conducted out of the pump.

I is a water gage secured to the chamber B which indicates the height of water in the chamber.

K is a by-pass or pipe leading from the chamber B to the chamber C. This pipe is outside ofthe chambers, as seen in plan in Fig. l, and is located near the bottom of the chambers, with each of which it connects, as seen in Figs. 2 and 6, where the openings of this pipe into the respective chambers are shown and marked with the said letter K; there is also in this pipe, outside of the chambers, a valve, or gate, 7c. Said gate valve 7c is for the purpose of keeping the proper normal water level in the chamber B and whenever the water gets below a certain level in the chamber B,the valve k is opened and the water is allowed to How from the chamber Cinto the chamber B; the exact amount of opening of the valve 7c will soon be found by eX- periments.

N is a rubber washer mounted on the shaft G between the pedestal a and the hood F2 i and is for the purpose of preventing Water from escaping, either from the hood or from the chamber C. l

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a condensing apparatus, a shaft partitions dividing the space between the disk curved to a point, in combination with a chamber for receiving and condensing steam, and a chamber for receiving the condensed steam with gases, said chambers being so arranged with reference to each other and with reference to said shell that the water may be taken from the rst chamber into said shell and thrown by the revolution of said shell into the second chamber, substantially as described.
